Definitions

  • Bootstrap power supplies are known. Most bootstrap power supply circuits are used in consumer electronic devices. Typical gate driver integrated circuits are designed to function with a bootstrap supply, for example.
  • FIG. 1 illustrates a typical bootstrap power supply arrangement 10 for providing power to a load 12.
  • a voltage source 14 has an associated current limiting resistor 16 and a rectifier 18.
  • a low side IGBT 20 switches on and off in a known manner.
  • a high side IGBT 22 is controlled by an upper gate driver 24.
  • a bootstrap capacitor 26 powers the upper gate driver 24.
  • the voltage source 14 charges the bootstrap capacitor 26 when the low side IGBT 20 is conducting. When the low side IGBT 20 is turned off, the bootstrap capacitor 26 is left floating. In that condition, the bootstrap capacitor 26 is connected with the upper gate driver 24 and the emitter of the high side IGBT 22. When the low side IGBT 20 is off, the voltage drop across it effectively changes the voltage that is used for charging the bootstrap capacitor 26. Under those conditions, the power supply for the upper gate driver 24 is unregulated. This is undesirable in many circumstances. For example, the unregulated power supply renders it of limited use for high voltage applications.
  • the voltage drops across the low side IGBT 20 can be significant compared to the voltage source 14. This produces a large variation in the charging voltage of the bootstrap capacitor 26 and makes it very difficult to remain within the desired voltage range for the upper gate driver 24. The large voltage variation also has a negative effect on the switching performance of the IGBTs 20 and 22.
  • JP H05 41397 U discloses a voltage type semiconductor device driving device for controlling each voltage type semiconductor device in an inverter formed by using voltage type semiconductor elements such as a power MOSFET, an IGBT. More particularly, it relates to a voltage type semiconductor element driving device suitable for applying an operating voltage to a control circuit from a DC power supply.
  • US2005/007076 A1 discloses a bootstrap capacitor charging circuit providing charging current limitation.
  • the present invention relates to an elevator system power supply according to the appended claims.
  • An exemplary power supply includes a low side switch and a high side switch.
  • a driver controls operation of the high side switch.
  • a bootstrap capacitor supplies power to the driver.
  • An energy storage portion is in parallel with the bootstrap capacitor to control any dropping of a voltage of the bootstrap capacitor.
  • a voltage regulator is in parallel with the bootstrap capacitor for limiting current provided to the bootstrap capacitor and for regulating a voltage of the bootstrap capacitor.
  • the energy storage portion may comprise a second capacitor.
  • the second capacitor may prevent a voltage of the bootstrap capacitor from dropping below a desired voltage until after the second capacitor voltage drops below the voltage of the bootstrap capacitor.
  • the voltage regulator may comprise a linear voltage regulator.
  • the voltage regulator may comprise a zener diode having a breakdown voltage selected so that the voltage source charges the bootstrap capacitor.
  • the zener diode breakdown voltage may be higher than a desired voltage of the bootstrap capacitor.
  • the zener diode breakdown voltage may be approximately 0.7 volts higher than the desired voltage of the bootstrap capacitor.
  • the voltage regulator may comprise a transistor having a base in series with the zener diode and wherein the transistor and the zener diode are in parallel with the bootstrap capacitor.
  • Further embodiments may comprise a DC bus coupled with the low side switch and the high side switch such that the switches control power supply to the DC bus.
  • the DC bus may comprise a high voltage DC bus.
  • An exemplary method of controlling power supply from a bootstrap capacitor to a driver that controls a switch includes providing an energy storage in parallel with the bootstrap capacitor.
  • the energy storage provides control over whether a voltage of the bootstrap capacitor drops below a desired voltage used to power the driver.
  • the voltage of the bootstrap capacitor is regulated using a linear regulator in parallel with the bootstrap capacitor.
  • Further embodiments may comprise using the linear regulator for limiting an amount of current supplied to the bootstrap capacitor.
  • the energy storage may comprise a capacitor and the method comprises preventing the voltage of the bootstrap capacitor from dropping below the desired voltage until the energy storage capacitor voltage drops below the voltage of the bootstrap capacitor.
  • Further embodiments may comprise using the high side switch for controlling power delivered to a DC bus.
  • the DC bus comprises a high voltage DC bus.
  • Figure 2 schematically shows a power supply 40 for providing power to a load 42.
  • the load 42 comprises a DC bus.
  • the DC bus comprises a high voltage DC bus.
  • One example includes voltages exceeding 120 volts on the DC bus. In an example used for an elevator system, the voltages may be on the order of 750 volts and up to 1200 volts.
  • a low side switch 44 and a high side switch 46 control power provided to the load 42.
  • the high side switch 46 is controlled by an upper gate driver 48.
  • a bootstrap capacitor 50 provides power to the upper gate driver 48.
  • a voltage source 52 is in series with a current limiting resistor 54 and a rectifier 56.
  • the voltage source 52 comprises a high voltage source.
  • the illustrated example includes an energy storage portion 60 in parallel with the bootstrap capacitor 50 and a voltage regulator 62, which is also in parallel with the bootstrap capacitor 50.
  • the energy storage portion 60 adds voltage in parallel with the bootstrap capacitor 50 to prevent the voltage of the bootstrap capacitor 50 from dropping until a voltage of the energy storage portion 60 drops below the voltage of the bootstrap capacitor 50. In other words, the energy storage portion 60 provides some control over whether the voltage of the bootstrap capacitor 50 will drop. This feature of the energy storage 60 allows for using relatively less expensive capacitors as the bootstrap capacitor 50, for example.
  • the energy storage portion 60 also allows for the voltage source 52 to be higher than the maximum voltage that can be provided to the upper gate driver 48. The presence of the energy storage portion 60 also promotes a faster, more effective charging of the bootstrap capacitor 50.
  • the voltage regulator 62 regulates the voltage of the bootstrap capacitor 50.
  • a linear regulator is used.
  • the voltage regulator 62 also limits the in rush current to the bootstrap capacitor 50, which facilitates using relatively less expensive capacitors.
  • the illustrated example allows for a bootstrap power supply to be used in a high voltage scenario because the energy storage portion 60 and the voltage regulator 62 dampen the effects of the voltage drop associated with the low side switch 44 turning off.
  • the energy storage portion 60 and the voltage regulator 62 also protect the bootstrap capacitor 50 and the upper gate driver 48 from experiencing a rapid increase in voltage.
  • the energy storage portion 60 and voltage regulator 62 also facilitate charging the bootstrap capacitor 50 more rapidly than was possible with traditional bootstrap power arrangements.
  • FIG. 3 schematically illustrates another example power supply 40 in which the energy storage portion 60 comprises a capacitor 70.
  • the capacitance of the bootstrap capacitor 50 and the energy storage capacitor 70 are selected so that the voltage on the bootstrap capacitor 50 will not drop until the voltage on the capacitor 70 drops below that of the bootstrap capacitor 50.
  • the voltage regulator 62 in the example of Figure 3 comprises a linear regulator including a zener diode 72.
  • the breakdown voltage of the zener diode 72 is selected to be higher than the desired voltage of the bootstrap capacitor 50 so that the regulator 62 is operative to charge the bootstrap capacitor 50.
  • the breakdown voltage of the zener diode 72 is approximately 0.7 volts higher than the desired voltage of the bootstrap capacitor 50 for powering the upper gate driver 48.
  • the linear regulator in this example includes a transistor 74 having its base in series with the zener diode 72.
  • a regulator resistor 76 and regulator capacitor 78 are also included in this example.
  • the switches 44 and 46 comprise IGBTs.
  • Other switch configurations such as an FET or another semiconductor switch may be used in some examples.
  • the example power supplies 40 of Figures 2 and 3 may be used in a variety of situations.
  • Figure 4 illustrates one example use of such a power supply within an elevator system 80.
  • the power supply 40 is used for powering the drive 82 associated with an elevator machine 84. Movement of an elevator car 86 within a hoistway 88 is controlled by operation of the machine 84.
  • the elevator system components require high voltage and the power supply including the energy storage portion 60 and the voltage regulator 62 allows for using a bootstrap power supply configuration in the high voltage elevator system environment.
  • One feature of the illustrated example power supplies is that for an elevator drive, there no longer is a requirement for expensive isolating transformers and separate switch mode power supplies for the gate driving circuitry.
  • each of the power switches e.g., the IGBTs 44 and 46 in Figure 3
  • the typical approach of using isolating transformers and separate switch mode power supplies for the gate driving circuitry tends to add significant cost to an elevator system's drive power supply. With the illustrated example arrangement, cost savings are possible and a robust solution for powering the upper gate driver 48 is realized.
  • the illustrated examples provide a cost and space optimal solution for an upper IGBT gate driver power supply.
  • the example power supplies minimize constraints otherwise imposed on a pulse width modulation by allowing for faster charging and a larger minimum on time for the low side switch.
